The Nyquist Keyboard - A Split 60% Ortholinear board

The Nyquist Keyboard - A Split 60% Ortholinear board

Posted by Danny Nguyen on


We've been working on a PCB for a split 60% ortholinear board that we're planning on stocking soon, and here's a sneak peek of what's coming up!

Couldn't have done this without /u/wootpatoot's awesome work and release of the Let's Split V2 files, which helped out a lot during the design process.


Each half of the board is a 5x6 matrix, but there is the option to have a 2u key in the lower corner in place of 2 1u keys. The spot for the 2u has holes for Cherry PCB mounted stabilizers. Here's some renders of the board with switches on it for both configurations:


There's also a spot on the PCB for a pushbutton switch to reset the Pro Micro for flashing. No more taking a wire/tweezers/screwdriver to jump the Reset and GND pins!

The Name

The name Nyquist comes from the Nyquist sampling theorem, which says that if you want to sample a signal to convert it from analog to digital and be able to uniquely reconstruct the signal later, then the sample rate has to be twice the bandwidth of the signal. So here, if you want to sample this PCB, you're going to need 2 of them. :p


The Nyquist can use QMK, and the code is basically a fork of the lets-split keyboard files. The pins used on the Pro Micro are the same as the ones used by the Let's Split, with the exception of the additional row of course, so it might be backwards-compatible with a Let's Split (we'll try it out and let you know).


Currently, we've got a test run of 30 PCBs (15 sets) being made right now so we can do some initial testing. Once everything checks out okay and any necessary modifications are made, a larger order will be placed for our store. Sign up for our newsletter, and be the first to know when you can order!
